Application led October 25, 1920. Serial No. 419,211.v A

To all 'whom t may concer/n Be it known that I, HARRY E. BoswELL, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have vinvented a new and useful Shoe Heel, of

which the following is a specification.

This inventionrelates to detachable heels, and Consists in the novel construction and arrangement hereinafter disclosed.

An object of the invention is to provide a heel adapted to be removably attached to a shoe whereby the same may be readily replaced without damage to the inner sole of' the shoe.

Additional advantages of the construction will be .apparent from the following detailed description thereof taken in connection with the accompanying drawing, in which- Fig. 1 is a side elevation of a part of the shoe, showing the heel construction -in vertical section'. y'

Fig. 2 is a bottom view of a portion of the heel showing the means for attaching the bottom section of the heel. l

Fig. 3 is a top plan view of the bottom section of the heel.

In the invention as illustrated in the drawing, the heel is made up of an upper section 1 that is nailed directly to the back portion of the shoe body by nails 2 that pass through the same into the inner sole 3 adjacent to the rear of the shoe body.

The metallic socket member 4 is embedded in the upper section 1 of the heel near the' center thereof. This socket member 4 has a bottom wall 5 in which there is a slot 6,

composed of a widened or enlarged central portion, and narrow portions extending ob` The bottom section 8 of the heel which may be rubber, leather or other appropriate elastic material, has a fastenlng device compr1sing a flanged stud 9. This fastening device is seated approximately at the center of the upper part of the `heel member 8, the stud beting provided with lugs l0 near its upper en A. plurality of flanged studs 11 are arranged about the stud 9 so that they will I register with the sockets 7, the stud being formed wlth balls 12 at their upper extremities. The stud 9 is inserted through the slot .6, the' lugs 10 extending into the narrow portion of the' slot. The member 8 is then given a slight .turn and the balls 12 are snapped into lace in the sockets 7. As the lugs 10 turn 1n the socket member 4, said lugs en .age the inclined cam-like upper surfaces o the bottom wall 5. As a result of this coopera-l tive engagement, the stud 9 is drawn upwardly into the socket member 4:, thereby clamping and rigidly holding the lower sec' tion 8 of the heel in connection with the upper section 1. At the time that the lower section 8 assumesY its proper position below the section 1, the balls 12 are snapped into the sockets 7, thereby holding the lower section 8 of the heel from turning.l When it is desired to remove the lower section 8, it is onl necessary to release the balls 12 from the soc et 7 and turn the section 8 to position tp permit the lugs 10 to pass out through the s ot 6.

It will be noted that the upper surface of the member 8 is slightly dished so that when the retaining devices are connected the two members 1 and 8 will be held tightly together. v 1

From the foregoing description of the construction it will be readily apparent that the lower section of the heel may be easlly adjusted in place and that, since the upper section is permanently fastened to the shoe body, there will be no damage thereto that results from the usual practice of withdrawing nails from the heel in the replacement of heels. I

I am aware that the invention may be modified in certain particulars without departing from the spirit and scope thereof. I do not limit myself, therefore, to unessential details, but what I claim and desire to secure by Letters Patent, is

1. In a heel, the combination of an u per section rigidly secured to the under si e of the shoe sole and having a flatlower wall, a socket embedded centrally in said upper section below the sole and having a slot throu h the lower wall thereof, cam-likesurfaces 1n said socket on opposite sides of saidslot, a lower heel section .having a concavity in its-upper end and having its side walls in continuation of the` side walls of the upper section when the upper end of the lower section is spread, a stud secured centrally to the upper portion of the lower section within said coneavity and arranged to extend into said socket, lugs on said stud arranged to engage the cam-like surfaces in said socket to spread the upper end of said lower section, and a number of releasable holding elements on said heel sections respectively between said Stud and the sides of the heel to prevent said lower section from turning and to hold the lower section in connection with the upper section, the elements on the lower section being within said concavity.

2. A heel, comprising' an upper section attacked to the under side of the sole and havmemset ing a flat lower wall, '.a socket embedded in the upper section and terminating at the lower wall thereof, cams in said socket, a lower section having arconcavity in its upper end, an element in connection with the lower section in said concavity for engaging said cams 'for the purpose described7 ,a number of additional sockets embedded. in one of said sections. and a number of balls secured to the other section to engage in said additional sockets to cooperate with said elements and s'aid cams to hold the lower heel section in connection with the upper section, and to prevent the lower section from turning, said additional sockets and said balls being substantially within the circumference of said concavity between said element and the outer border of the concavity.
